ELECTRlC-MQTOR-CAR TRUCK.

SPECIFICATION forming part of Letters Patent No. 455,581, dated July '7,1891.

Applieation filed March 9, 1891.

To cbZZ whom it may concern:

Be it known that 1, JOHN F. SEIBERLING, a citizen of the United States,and aresident of Akron, county of Summit, and State of Ohio, haveinvented a new and useful Improvement in Electric-liotor-Oar Trucks, ofwhich the following is a full, clear, and exact description, referencebeing had to the accompanying drawings, making part of thisspecification.

My invention relates to the manner of com-* bining an electric motorwith a street-railwaycar truck, which said motor is designed to propel;and it consists in an arrangement whereby the armature-shaft is geareddirectly to the truck-axles, and incidentally in certain features ofconstruct-ion and arrangement of the truck and motor frames and partsthereof whereby the above arrangement of gearing is attained,ashereinafter described and claimed.

In the accompanying drawings, Figure 1 is a plan view of the car-truckwith the motor applied, showing my improvements with the gears insection. Fig. 2 is a side elevation of the car-truck. Fig. 3 is an endview of the motor-frame, showinga part of one of the truck cross-beamsto which it is attached. Fig. 4. is a side elevation of said motor-framewith the truck cross-beams and one of the armatureshaft pinions insection. Fig. 5 is an end view showing the truck-wheels in elevation andthe side sills and bevel-gear in section, and Fig. 6 is an end view ofone of the side truck-sills and of the spring-bracket connectedtherewith.

The main object of my invention is to reduce the expense andcomplication and to diminish the weight and wearing of the parts in theconstruction of electric-motor trucks as heretofore used. To this end Imount a single' motor on the main truck-frame that supports thecar-body, instead of employing a secondary frame for said purpose.

accommodate the motor-frame B between them. The side sills,and also thecross-beams Serial No. 384,324. (No model.)

Z) b, are preferably made of channelediron, as v giving the requiredrigidity without unnecessary weight of materiahand the cross-beams 5 5 bb are further stiffened by means of oblique braces o c, which connect,them to the side sills at points midway between said sills. The ends ofthe side sills are further connected outside of the wheels by end sillsb.

The outer faces of the channeled side sills are straight planefaces,.and to these, adja- 'cent to the ends and between the pedestals"and adjacent thereto, are secured brackets d cl d d, bifurcated in theirlower pendent portions to form each a yoke 61 to embrace the springssupporting the car-body and provided v in their upper portions, whichare secured to the outside of the sills, with sleeve-sockets d toreceive sliding standards e,shouldered near their lower ends, saidshoulders resting on collars or washers e, between which and thebase-plates (1*, connecting the bifurcated lower ends of the spring yokeorbrackets cl (1', the supporting-springs d are secured, surroundin gthe lower ends of the standards,whichplay loosely through said washerse. The upper ends of the standards have longitudinallyarranged bars orstraps c secured to them, which in practice aresecured also to the lowerfaces of the sidesills of the car-body.

The lower endsof the pedestals a and sprin g1 brackets (l and d areprovided with foot flanges, through which all on the same side of thetruck are bolted to a connecting-bar f, which materially stiffens andstrengthens them.

f f are obliquely-arranged braces connected at their lower inner ends tothe pedestalso and at their upper outer ends to the 0 sills A forfurther stiffening the pedestals and supporting the ends of the sills.

F and F are the axles, provided each near the center of its length witha bevel-gear H. These bevel-gears face" inward toward each other fromopposite sides of the center of the length of the-axles, sufficientlyremoved fronr such center to accommodate between .them' bevel-pinions gg fast on opposite ends of the armature-shaft g and meshing with saidbevel-gears for driving them and the axles.

The motor-frame (indicated at B) is made yoke-shaped, approximating anopen ellipse in form in plan View, as shownin Fig. 1,with

shaft g has its bearings.

' armature-shaft boxes being located in the upits ends B adjacent to thecross-beams b l) bent or crooked upward and recessed underneath toreceive and permit vertical adjustment of the boxes in which thearmature- This motor-frame fits snugly between the cross-beams b b andthe ends thereof at points above the boxes are secured to said beams.The frame B is provided on its sides with lugs or ears 0' 0,

10 through which it is connected by adjustable bolts 0 to lugs or ears 0on the braces c, and is further provided at its ends with ears 2' and1', one on its lower and the other on its upper face or edge, as shown,and to these ears, rods,

or braces I and I are adj ustably secured by nuts i 2' on each side ofthe lugs, said rods extending the one I nearly horizontally outward andbeing connected .rigidly with a sleeve I, in which the axle F or F isjourzo naled, and the brace 1 extends obliquely down to and connectswith the bar 1 near said sleeve, as shown. By this arrangement when themotor-frame B is secured in place between the cross-beams b'b of thetruck- 2 5 frame and the braces I and I are connected therewith andproperly adjusted by means of the nuts 1' i the ends of the motor-frameare adjustably supported and a strong bracing connection is made betweensaid motor-frame 0 and the truck-axles, which effectually pre ventstheir relative displacement and serves to hold the pinions g and 9always in proper working relation to the bevel-gears 1-1 on the axles.The sleeves I and their brace-connec- 5 tion with the motor-frame arearranged on opposite sides of the pinions g and g from the bevel-gears HH and as near to said pinions as practicable, as giving them the mosteffective relation to the gears, and in which 0 they serve also tostiffen the cross-beams b b centrally of their length.

The cross-beams b b have a flange j proj ecting therefrom above thejournal ends of the armature-shaft, said flange being perforated toreceive pendent bolts 70 70, extending down through lugs on theprojecting ends of the armature -frame, which bolts support the frameand connect it to said cross-beams. Between said bolts a set-screw 70'passes down '50 through the fiangej, its lower end resting on theprojecting half journal-box ends L of the frame B and serving to forceit downward when required. By this arrangement of bolts and set-screwthe motor-frame is not only 5 5 firmly secured to the cross-beams b b,but is also rendered capable of being adjusted up and down as may bedesired to bring the bevel-pinions in proper relation to thebevelwheels. The lower half of the box L is connected with the upper bymeans of a U- shaped loop-bolt P, the loop of which passes under saidhalf, the ends thereof passing up through the projecting journal-boxpart L of the ends of the armature-frame and being secured by suitablenuts, as shown. These wardly-crooked ends of the motor-frame in recessesin the under side thereof, as described, and projecting from said ends,by simply removing the loop-bolts Z and releasing the lower half-boxes Lthe armature-shaft and armature can be readily removed when required.The armZ of the journal-box projection L is extended on the sideadjacent to the bevel-wheel H and has an outwardly-projecting arm Z onits end, reaching behind said bevel-wheel. This arm Z has a shorthorizontal slot Z formed in it, in which is secured ashortlongitud-inally-arranged shaft m, on the outer end of which is journaleda smooth-faced roller m, which rests and rolls in contact with a smoothrolling-surface at h on the back of the bevel-gear H. The shaft m isadjusted in the slot Z by means of a setscrew Z which presses against itand by means of which the roller m can be held snugly against thebevel-Wheel for preventing the latter from being thrown out of properworking relation to its actuating-pinion by the lateral thrust of saidpinion thereon.

The pinions g and g are shown each ex tended beyond its toothed portionto form on the end of the armature-shaft a smooth-faced beveled roller 9which rests and rolls in contact with a smooth annular rolling-surfaceat h, on the face of the bevel-wheel I'l inside of the teeththereon.This prevents the teeth of the pinion from being crowded into andmeshing too deeply with the teeth of the bevel-wheel, and in connectionwith the rollers m insures the correct and easy working of the gears.

The rollers on the ends of the pinions g 9 may be made separate fromsaid pinions and loose on the ends of the shaft, in which case theycould be varied in diameter.

The roller m by preference is connected to the projecting part of themotor-frame, but may have its support on any suitable part of thetruck-frame, as its ofiice is to prevent lateral thrust from beingimparted to the bevelpinion through the truck-frame.

The pole-pieces or magnets (indicated at B B are connected with thesides of the motorframe, and together with the armature (indicated at G)and the commutator (indicated at G may be of any usual or preferredconstruction, as they form per 36 no part of the improvement hereinclaimed.

Having now described my invention, I claim as new and desire to secureby Letters Patent 1. The combination of a car-truck having the frameside sills arranged outside of the wheels and connected together by twocrossbeams between the wheels, and an electric motor arranged betweenthe cross-beams and adjustable relatively thereto, means for adjustingsaid motor, the bevel-pinion on the armature-shaft and the bevel-wheelon the truck-wheel axle arranged to intermesh with said pinion,substantially as described.
